Many researchers now believe that it does affect both your physical and your mental state. From daylight, our bodies absorb vitamin D through the skin. Old people especially need thisvitamin to strengthen their bones. Certain skin diseases also benefit from exposure to sunlight. Lessdirectly, light absorbed through the eye can stimulate hormone* production, which in turn affectsour mood. Recent research has established that some people bee depressed in winter, when the daysare dark and most people spend less time in the open air. These people find that they lack energy, have difficulty concentrating, and often gain weight inthe winter months, When spring es, these symptoms disappear. Reseamhers have called thiscondition SAD -- seasonal affective depression. The condition can be treated by exposing patients to special lights, known as full-spectrumlights. Ordinary light bulbs produce light at the red end of the spectrum, and fluorescent lights are inthe green-yellow range. Full-spectrum lights*, on the other hand, reproduce more accurately theeffects of natural sunlight. As well as helping sufferers from seasonal depression, this lighting hasbeen used to treat patients suffering from jet-lag. It is also being tried as a means of improvinglearning in school-children in Russia and America, and improving the efficiency of Japanese factoryworkers. If you spend a lot of time in artificial light or indoors, or if you feel depressed in winter, youshould try to spend more time in the open air. Young people need at least fifteen minutes a day in realdaylight in summer, thirty minutes in winter. Old people, who risk vitamin D deficiency, shouldspend even longer exposed to natural daylight.Exercise A:1.
